7 Claims.

My invention relates to smoking pipes.

It has among its objects to provide an improved pipe wherein, while the pipe is free from obstruction during loading and lights more easily and burns more uniformly, it is made possible to pro:

vide a cool smoke and to collect the nicotine and minimize the discharge of objectionable matter into the smokers mouth. A further object of my invention is to provide an improved appliance 1 adapted to use in connection with any standard form of pipe while performing the above'functions, and further adapted to be readily and quickly applied to or removed from a pipe while facilitating the emptying of the latter, .and also being adapted to be readily cleansed andto be inexpensively manufactured. These and other objects and advantages of my improved construction will, however, hereinafter more fully appear.

In the accompanying drawing I have shown for purposes of illustration three embodiments which my invention may assume in practice.

In the drawing- 1 1 Figure l is a central vertical section through 1a pipe equipped with one form of my improvement;

Fig. 2 is an enlarged side elevation of the appliance shown in Figure I, removed from the D p Fig. 3 is a like view of a modified form of appliance, and 1 1 Fig. 14 is a like view of a further modified form of the same. I

Referring first to the illustrative form of the construction shown in Figures 1 and 2, it will be observed that I have shown a pipe I of a standard,

construction having a usual bowl 2 and air passage 3 in the stem 4 and also provided with my improved appliance, generally indicated at 5, in the bottom of the bowl 2 and between the latter and the air passage 3. 1

My improved appliance is of generally ball, or spherical, form and preferably is made of light material, such, for example, as aluminum and in all the forms shown has a rigid outer crust.

Further, in the formshown in Figures 1 and 2,

tinuing to provide-spaced passages inside the outer surface of the ball; Preferably, however, these cutsare so disposed as to be distributed uniformly over the entire peripheral surface of the ball. Further, while in this form of my invention I preferably utilize a solid ball, I may use a hollow ball, if desired. Further, while aluminum is preferred on account of its lightness and afiinity for heat and itsk'nown adaptability to be quickly and completely cleansed, it will be understood that other-metals, materials or com-1 positions may be used,if'desired, as, for example, terra cotta.

As a result of my improvement, the cuts or grooves 6 cooperate to provide a series of passages so disposed that however the ball 5 is droppedinto a pipe bowl, it will locate itself at the bottom of the bowl and over the intake of the air passage 3.

Thus, while in no way obstructing loading, ital- 1 ways functions in any position to providea series of air passages leading around the ball to the air passage 3 in thestem. Also due to the upward projection of the upper surface-0f the balLthe ball, so that lighting is expedited. Thus,jmy improved construction is such as to make burning 1 during both lighting and smoking, markedly more uniform. Moreover, the smoke passing out through the passage 3 is cooled dueto the heat absorptive qualities of the ball, while nicotine or]:

other substances entrained with the smoke, are

collected upon the walls of the cuts or grooves in such manner as to minimize the amount of the same transmitted to the mouth and lungs of the smoker.

1 In the use of my improvement, it will be evident 1" that my improved ball will tend to locate itself in the correct position when simply dropped intothe bowl of a pipe. Further, when it is desired to remove the ball, all that it is necessary to do is to invert the pipe.- The presence of theball further tends to eliminate the formation of the,

1 tobacco is not packedtight over the sides of the usual wet caking over the inlet of the air passage 1 1 3, while when the ball is removed by inverting the pipe, or knocking out the same in a usual manner, the ball will carry with it any remaining unburnt tobacco, or ashes. Obviously, when removed, the ball may also be readily cleansed for further usein any suitable manner, as, for example, by washing it under running hot water.

Here also it will be understood that while I have shown only a ball of a single size, I contemplate the use of balls of such different sizes as to be adapted to the particular size of pipe, as, for example, small, medium and large balls adapted to jlO a use in small, medium and large pipes.

It will also be evident that, if desired, the ball may be of such size as when pressed downward in the bottom of the bowl, to frictionally engage the 7 Wall of the bowl and remain therein when the pipe is emptied, while still being readily removable when the pipe is tapped more briskly during emptying. In all sizes, it will further be noted that any tendency to draw tobacco into the stem, in such manner as to plug thesame, is

' also effectively minimized. These and other advantages of my improved construction will, however, be clearly apparentto those skilled in the l art.

of ball, generally indicated at 'l, which may be used if desired. I This ball, however, is provided with a rough surface, indicated at 8, and is also preferably madeof aluminum. Obviously,iwhile in this form of my invention, the passage means are not as definitely defined as in Figures-1 and 2, such passage means will be provided by the rough surface. The same applies to the modification shown in Figure' wherein a hollow aluminum ball 9 is provided having an outer rigid shell provided with perforations l distributed uniformly over the same and having communicationprovided between one another andthe bowl 2 and air passage 3 by a, hollow center or chamber I l. While not preferred for various reasons, including the fact that they are not so readily cleaned as the construction shown in Figures 1 and 2, it will be evident that these modified constructions will function generally'similarly in view. of their ball form and the uniform distribution of the air passagemeans provided by the rough surface 8 and perforations ill. v

As a result of my improved construction, it will be observed that in all forms a ball is provided the passage means are so formed therein and distributedthereover asnot only to permit the periphery of the ball to be readily cleansed, but also to permit these passage means to be so distributed over the outer shell or surface of the ball as to enable the latter to be dropped in any position into the pipeand function equally well in all positions.

While I have in this application specifically described three forms which my invention may assume in practice, it will be. understood that these forms of the same are shown for illustrative purposes, and that the invention may be modified and embodied in various other forms without departing from its spirit or the scope of the appended claims. 1.

What I claim as new and desire to secure by Letters Patent is: e

1. A smokers accessory for insertion in the'bot- In Figure 3, I have illustrated a modifiediform' tom of a pipe bowl, comprising a substantially spherical member having a rigid outer crust and passage forming means therein forming passages of predetermined size and direction, some of said passages being located transversely to others so that in whatever position the member is placed within the bowl there will be communication for smoke between the bowl and the pipe stem.

' 2. A smokers accessory for insertion in the bottom of a pipe bowl, comprising a substantially spherical member having a rigid outer crust and passage forming means therein forming passages of predetermined size and direction, certain of said passages being located transversely to others 'solthat. in every position of said member within the pipe bowl like communication will be provided for smoke between the bowl and stem.

3. A smokers accessory for insertion in the bottom of a pipe bowl, comprising a substantially spherical member having a rigid outer crust and of predetermined size and direction, some of which are located transversely to others, said member providing in every position thereof in the bowl an arcuate supporting surface for the tobacco therein while also providing communication for smoke through said means from the bowl to the pipe stem.

'4=.-A smokers accessory for insertion. in the,

bottom of a pipe bowl, comprising a substantially spherical member having a rigid surface and havgrooves in the surface thereof forming smoke conducting passages of predetermined size and direction, certain of said passages being located transversely to others so that in all positions of said member in the bowl the portion of said member which is in contact with the tobacco provides communication through said grooves from the bowl to the stem.

v6. A smokers accessory for insertion in the bottom ofa pipe bowl, comprising a substantially spherical member having a rigid outer crust and a plurality of surface projections thereon adapted to engage the pipe bowl and space the surface of said member therefrom to provide smoke conducting passages between the bowl and stem in any position of insertion of said member in the bowl.
